Just curious if anyone else has had this problem. I noticed this with my iPhone 7 Plus over the weekend; when bluetooth is enabled, my wifi download speed drops significantly. The upload speed doesn't seem to change much. This only happens on 2.4ghz but not 5ghz. I've reproduced this in two different locations with four different wifi access points and three different routers. The problem doesn't happen with my iPhone 6s Plus on the same access points. Since I upgraded to the 7, I've noticed occasionally I'll lose connection to all bluetooth devices. I've seen this happen at home and in the car, so I don't think it's an interference related issue. I'm guessing the problem is a bad bluetooth chipset. Apple is going to send me a replacement after I confirm that neither resetting network settings or doing a factory reset fix the issue (didn't have time to try those fixes today). I was just curious if anyone else has experienced this and if the problem could be anything other than a bad bluetooth chipset... such as a bluetooth application.
